Currently I work as a .NET C# programmer, quite fresh faced at that (only been working professionally for 8 months) I'm enjoying what I'm doing, but I'm now thinking ahead for other languages to learn.

I've heard from quite a few seasoned developers that they reckon it's worth getting in to HTML5.

Before I asked this question I read a few of the other questions similar to this, but most were dated back a few years. I'm wondering what your advice would be to an aspiring programmer, what I should avoid going for (i.e. as I understand it Flash is essentially going to be phased out due to HTML5)

I was looking in to WPF and the more updated .NET technologies, but someone advised me that WPF stuff will probably be redundant in the future.

Thanks for your advice and opinions :)
